SPEUIFICATION forming part of Letters Patent No. 775,977', dated November 29, 1904.

l Application `tiled March 5, 1964. Serial N o. 196,677. (No rnodel.)

yTo @ZZ whom t may concern:

'nectingone car' to another throughout the entire length of a train of cars, said draftrigging Vybeing independent of the center or draw sills of the car-frames, so thatthe strain upon said sills of the car-frames is lessened and the train started or stopped by' a continuous iiexible draft-rigging extending throughout the entire length of the train.

The object of my invention is, further, to save the wear and tear upon the car-body incidentV tothe shocks and stresses caused by the cars being coupled, thus saving the running-gearV 4and freightfrom injury and also causing a 'train of cars to start and stop with more flexibility and freedom fronti jars.

The invention consists of a car-frame, adraW-bar frame supported upon, extending longitudinally of, and adapted to slide' upon,

said car-frame, with a draw-bar attached to each of its opposite ends, combined with a spring interposedbetween said car-frame and draw-bar frame, said spring being adapted to. receive an' endwise thrust imparted to the draw-bar frame and transfer said th rust to the car-frame.

The invention again consists in the instrumentalities hereinbefore set forth in combination with trucks pivoted to said car-frame.

rlfhe invention again consists in a series of car-frames connected together by a draft-rigging comprising a series of draw-bar frames, each of said frames being adapted to slide longitudinally upon itsV respective car-frame and I l' having a draw-bar at each of its opposite ends adapted to slide uponsaid draw-bar frame, a

spring interposed between each of -said Acarviframes and its; respective draw-bar frame, and

,sills 11.

means to connect each adjacent pair of drawbars together. l

The invention finally consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to, the drawings, Figure is a` p lanview of a car-frame of well-known construction with my improved draft-rigging attached thereto. Fig.l 2 is an enlarged plan of a portion of the endof a 'car-frame with my improved draftrigging attached thereto.-

Fig. 5 is a. section, partly in elevation, taken on line 5 5 ofFig. 4, illustratingftwo draw-bars attached lone to the other by couplers. Fig. 6 is a detail section on -line 6 6 of Fig. 4. Fig. 7 is a plan view of a channel-bar tie-plate.' Fig. 8 isa side elevation, on a reduced scale, of two drawbar frames joined'together by couplers, said frames being partly broken away and shown in connection with the end sills and body-bolsters of two car-frames.

Like numerals refer to like parts throughout the several views of the drawings.

In theV drawings, 10-is a car-frame of Well'- known construction. 11 11 are the end sills; 12 12, the body-bolster; 12', thetruck-bolster, and

truck-frame is pivoted to said car-frame; 13 13, the cross-frame tie-timbers; 14 14;, side sills; 15 15, intermediate sills, and 16 16 the center sills. Between the center sills 16 are two channel-irons 17 17, which extend throughout the entire length of the frame to within a short distance of the inside of each of the end These channel-irons are fastened together by tie-plates 18, which are fast to the lower flanges of said channel-irons and extend across therebeneath, resting upon the .top of the body-bolster 12. Tie-plates 19 are fastened to the web of thechannel-irons 17 and'to each other and form an 1additional means of rigidly securing said channel-irons one to.` the other. Tie-plates 2O extend across the top of the channel-irons 17 and are rigidly-bolted to the center sills 16, thus form- 122 the king-bolt, by means of which the IOC ihg guides to prevent the channel-irons from compressed by the follower-plate 4Qand strap.
